I am going to experiment with these and the Chocolate Brownie Cookies and see how well they will hold in a Food Saver cannister. They are so tender that they would get crushed in a Food Saver bag. I have a couple of events in Dec. that I bake for. I usually save those two for last because they do go stale so quickly. With the cannister and the air vacuumed out I can do a 1 week test, if okay reseal and try what 2 weeks does and so on. I'll report next fall.
